The present specification proposes a discontinuous reception operation method characterized by: in a wireless communication system, a terminal in which a plurality of cells are configured performing a physical downlink control channel (PDCCH) monitoring on-duration; receiving bandwidth part (BWP) setting information, wherein the BWP setting information informs a specific BWP; receiving a PDCCH on the basis of the PDCCH monitoring, wherein the PDCCH includes dormant indication information for a specific cell from among the plurality of cells of the terminal; and activating the specific BWP on the basis of the dormant indication information indicating non-dormancy.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The method of claim 1, wherein the UE does not perform PDCCH monitoring or does not receive a physical downlink shared channel (PDSCH) on the dormant BWP.
3. The method of claim 1, wherein the dormant BWP is a BWP set by higher layer signaling.
4. The method of claim 1, wherein a maximum number of BWPs configurable for a cell for the UE is four.
5. The method of claim 1, wherein the UE receives a physical downlink shared channel (PDSCH) or the PDCCH on the specific BWP.
6. The method of claim 1, wherein the PCell is a cell in which the UE performs an initial connection establishment procedure or a connection re-establishment procedure, and the SCell is a cell in which additional radio resources are provided to the UE.
